CLI-723 Cleanup legacy resources unconditionally to support downgrades

[georgii-borovinskikh-sonarsource]

Part of CLI-505

---

Summary by Gitar

• Integration cleanup logic:
  • Modified IntegrationInstaller to invoke cleanupRecordedLegacyInstallations unconditionally before processing resources.
  • This ensures legacy resources are removed even if the current state records a newer version, supporting downgrade scenarios.
• Testing:
  • Added a unit test in registry.test.ts to verify that legacy cleanups execute during re-installation after a file state reversion.
